Reinforced design for heavy-duty use
- Extruded PVC center cores provide the strongest backbone, with round holes that evenly distribute stress and minimize the risk of cracking or collapse under heavy debris loading.
- Wider, break-resistant bands keep pleats evenly spaced, preserve optimal flow, and prevent pleat flutter caused by turbulence in the housing.
Premium filtration media for clearer water
- High-quality polyester media delivers durability and efficient filtration, helping you achieve clearer water and longer filter life.
- Sharp pleat folds with a unique synthetic fiber construction allow dirt to penetrate deep into the pleats, boosting filtration efficiency and making cleaning easier.
- Antimicrobial end caps (reinforced for added strength) resist odor-causing bacteria and mold, helping keep your filter and pool/spa environment fresher.
End caps and fittings that simplify maintenance
- End caps with integrated fittings eliminate the need for PAD adapters, improving flow and installation ease.
